So, what ever happened to.....
Hate me if you must, but my work truck is a completely stock looking rust free, dent free 90 Chevy 1/2 ton with a 96 - 330hp LT1 engine and T56 six speed manual trans and though its not customized in any way outside of what you cannot see and its a Chevy, it cruises high speeds, corners like a sports car and gets 26 mpg on the freeway.
BTW, here in Grants Pass Oregon, we haven't any inspections or smog laws..
